TlME RECORDER.

SPECIFICATION forming part of Letters Patent No. 678,777, dated July 16, 1901.

Application filed October 9,1900. Serial No. 32,475. (llo model.)

To all whom, it may concern:

Be it known that 1, PETER G. GInoUn, a citizen of the United States, and a resident of Binghamton, in the county of Broome and State of New York, have invented a new and useful Improvement in Time-Recorders, of which the following is a specification.

My invention relates to a time-recorder,

with the object in view of providing effective IO means for advancing the minute-wheel at the beginning of a new hour promptly up to the position of zero, which it should occupy in order that the record of the succeeding hour may never be coupled with the fifty-ninth minute of the preceding hour.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure 1 represents a section from front to rear through so much of the recording mechanism as is necessary to illustrate my invention, showing the means employed for causing the minute-wheel to jump its space. Fig. 2 represents the said portion of the recording mechanism in front elevation. Fig. 3 is a view in detail showing the reverse side of the wheel for causing the minute-printing wheel to skip and the actuating parts in immediate contact therewith; and Fig. 4 is a section in detail through the support of the drive-wheel which engages the minute-printing wheel, showing the manner in which it is mounted.

The year-wheel is denoted by a, the meridian wheel by b, the minute wheel by c, the hour-wheel by d, the day-wheel by e, and the month-wheel by f.

The meridian and hour wheels I] and d are connected to rotate together and are driven by'means of lantern-teeth c, projecting from the side of the rim of the meridian-wheel C, while the minute-wheel cis mounted to move independently of the meridian and hour wheels and is driven by means of a gearwheel h, fixed to rotate therewith.

As my present invention is limited to the means for causing the minute-wheel c to promptly assume the position of zero at the beginning of the'hour or at the moment the number representing the succeeding hour is moved into position, I have shown the mechanism which immediately coacts therewith,

and leave it to be understood that the several wheels are to be actuated by such approved means as have been devised therefor.

In the present instance the spring-actuated lever t', with its pivoted nose or driving-pawl t" for actuating the meridian and hence the hour wheel, carries a laterally-projecting pin j, in position to strike the slanting face of a projection 70' on the side of the gear-wheel Z, which intermeshes with and drives the gear h on the minute-wheel c, the face of the projection 70 on the drive-wheel Zbeing extended at an angle to a radial line, and in such di rection that when the pin j strikes it during the inward. movement of the lever tit will force the gear-wheel lforward a distance sufficient to drive the minute-wheel 0 fully up to the position of zero-viz, the position which it should occupy at the beginning of the hour. The slanting surface of the projection 716 is so placed upon the wheel [that it will be in position to be engaged by the pin j on the lever i when the lever is allowed by the cam on on the actuating-shaft 'n to move forward or inward under the impulse of its actuatingspring 0 to advance the meridian and hour Wheels. The sudden forward jump of the minute-wheel takes place, therefore, at the moment the hour-wheel presents the next succeeding hour, and hence if there is the slightest tendency of the minute-wheel to drag and still present the fifty-nine number of minutes instead of the zero number with which the hour begins it (the minute-wheel) will be promptly forced out of its backward position and up to the position which it should occupy at the beginning of the new hour.

The specific structure and arrangement of parts by which the drive-wheellis permitted to jump forward under the impulse of the pin j against the projection 70 is as follows: The wheel Z is loosely mounted on the reduced end of a hub 19, secured to the shaft '17. by a set-screw q. The wheel is held in po- 5 sition on the reduced end of the hubp by means of a collar r, fixed on the shaft by means of a set-screw s, with its inner face against the end of the hub p, leaving a sufficient space between a flange on its inner face and the flange on the hub 19 for the free rotary or rocking movement of the wheel Z.

The flange ten the inner end of the collar 0" is provided with a short recess u to receive a laterally-projecting pin 1), fixed to the wheel Z. The pin e within the recess it limits the rocking movement of the wheel Z, while permitting it to move relatively to its hub a distance sufficient to jump it forward the extent desired at the end of the hour. The said wheel Z is normally held with its pin 1) against the rear wall of the recess a by means of a spring 20, fixed at 90 to the periphery of the collar 0 and having its free end y hooked over the pin 0.

In operation when the lever 2 moves in wardly at the end of the hour and strikes its pin 7' against the face of the projection 7.: on the wheel it forces the wheell forward to the limit of its hour position, the spring to yielding to permit the pin '0 to move toward the forward wall of the recess a. In this position the Wheel Z will rest until the shaft a, carrying the collar r, has been rotated by the action of the time mechanism (not shown) to bring the rear wall of the recess u again in contact with the pin a), when the wheel Z will be driven continuously by the shaft n, as usual, until the completion of another hour, when the forward jump will again take place, provided the wheel at chances to be in the slightest degree backward of the position which it should occupy at the end of the hour. This provision for securing with certainty the proper record of the minute-wheel at the beginning of the hour is a very important one, since it provides against the possibility of the record at the beginning of the hour presenting the new hour and. fiftynine minutes instead of the new hour and no minutes, a defect which when it occurs, as it has been known to repeatedly, becomes serious in estimating the time of the workmen.

It is obvious that changes might be resorted to in the form and arrangement of the several parts without departing from the spirit and scope of my invention. Hence I do not wish to limit myself strictly to the structure herein set forth; but- What I claim is- 1. The combination, with an hour-wheel and means for moving it stop by step, of a minutewvheel and means for moving it continuously, the said minute-wheel being free to be temporarily shifted independently of its continuous movement, and the driving mech' anism of the minutewheel being under the control of the driving mechanism of the hourwheel to be shifted by said hour-wheel-driving mechanism simultaneously with the step movement of the hour-wheel, substantially as set forth.

2. In combination, an hour-wheel, means for moving thehour-wheel step by step, a minute-wl1eel, a drive-wheel for imparting a continuous rotary movement to the minutewheel, the said drive-wheel being mounted to rotate to a limited extent independently of its support, and a spring for holding the said drive-wheel normally at one extreme of its limited movement, the said drive-wheel being under the control of the houuwheel-driving mechanism to be rocked independently of its support against the tension of said spring, substantially as set forth.

3. The combination with the hour-wheel and means for operating it step by step, of the minute-wheel, a drive-wheel for continuously rotating the minute-wheel, a supporting-shaft, a hub having a bearing for loosely mounting the drive-wheel thereon, means for fixing the hub to the shaft, a collar for holding the drive-wheel on the hub and limiting its rotary movement independent of its support and a spring attached to the collar and wheel for holding the wheel normally at one extreme of its said limited movement, the said drive-wheel being under the control of the hourwheeldriving mechanism to be rocked relatively to its support, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 5th day of October, 1900.

PETER G. GIROUD.
